Question

If f(x)=x+1 then f(f(f(y+2) is

Answer 1

Answer:

take it bro pls follow me

Answer 2

Answer:  f(f(f(y+2)))  = y+5

Explanation: f(x)=x+1

            then f(f(f(y+2)))

Step 1 -∵ x = y + 2

  ∴ f( y + 2 ) = y+2+1

    f( y + 2 )  = y+3

f(f(y+2)) = f(y+3)

Step 2- x = y+3

f(y+3) = y+3+1

f(f(y+2)) =f(y+3) = y+4

f(f(f(y+2))) = f(f(y+3)) = f(y+4)

Step 3- x = y+4

f(f(f(y+2))) = y +4 +1

 f(f(f(y+2)))  = y+5
